We consider 1-way quantum finite automata (QFAs). First, we compare them with their classical counterparts. We show that, if an automaton is required to give the correct answer with a large probability (over 9/10), then the power of 1-way QFAs is equal to the power of 1-way reversible automata. However, quantum automata giving the correct answer with smaller probabilities are more powerful than...

Starting in the early 90’s, numerous digital watermarking schemes were introduced to combat the unauthorised copying of digital multimedia on the web. Initially techniques were proposed which manipulated data in the spatial domain to embed the secret information. However Cox et al. progressed to use a spread spectrum technique, which alters components in the frequency domain of an image to hide...

While the genomes of many organisms have been sequenced over the last few years, transforming such raw sequence data into knowledge remains a hard task. A great number of prediction programs have been developed that try to address one part of this problem, which consists of locating the genes along a genome. This paper reviews the existing approaches to predicting genes in eukaryotic genomes an...

With 123 million Internet users, China represents a phenomenal potential market for e-business. The astounding success of China in attracting foreign direct investment (FDI) can be partially explained by a series of reforms of policies, regulations, and laws. Can the introduction of China’s new electronic signatures law produce the same results for e-business in China? This paper analyses the e...

Numerous methods have been developed for inferring gene regulatory networks from expression data, however, both their absolute and comparative performance remain poorly understood. In this paper, we introduce a framework for critical performance assessment of methods for gene network inference. We present an in silico benchmark suite that we provided as a blinded, community-wide challenge withi...

Public key cryptography has become an important means of ensuring confidentiality, notably through its use of key distribution, where users seeking private communication exchange encryption keys. It also features digital signatures which allow users to sign keys to verify their identities. This research presents the innovations in the field of public-key cryptography while also analyzing their ...

INTRODUCTION Contemporary daily life is more and more characterized by ubiquitous interaction with computational devices and systems. For example, it is commonplace for a person walking a busy street, to be engaged in conversation with a distant person using telephony, while simultaneously receiving directions via a GPS-enabled web application on their mobile device. This overwhelming increase ...

BACKGROUND The patients' role in assessing health care quality is increasingly recognized. Measuring patients' specific experiences and needs generates concrete information for care improvement, whereas satisfaction surveys only give an overoptimistic, undifferentiating picture. Therefore, this study aimed to investigate possible weaknesses, strengths and needs in fertility care by measuring pa...
